It has a temperature of 15 million kelvins and is made of hot, dense plasma. It is 34% of the sun's mass and is made of mostly hydrogen and helium.

The radiation zone is the area of the sun where energy is transported to the exterior by radiative diffusion and thermal conduction. This layer has a temperature of 1.5 million kelvin and the temperature is gradient.

The convective zone is an area unstable to convection and the energy in this region is transported by convection. The movement of plasma forms this circular convection current where it cools near the surface and warms up near the core.

It is composed mostly of hydrogen and helium. It is the deepest region of a luminous object.

The chromosphere, which can only be seen during eclipses,  is located above the photosphere and is usually a redish color. It cannot be seen normally because of the brightness of the photosphere.

The solar corona is the aura of plasma that surrounds the sun. It extends millions of miles into space and can be seen during a total solar eclipse. It is around 1 million kelvins in temperature and is separated from the photosphere by the chromosphere.

It is caused by concentrations of magnetic field flux that inhibit convection.

They contain cool plasma so it is over 100 times more lit and dense than coronal plasma.

It releases clouds of electrons, ions, and atoms throughout space, which can affect normal processes on Earth.

They occur when the magnetosphere is disturbed by solar wind, which emits variations of light in several tangible complexities.
